Just make sure you install the latest unofficial patch properly, or the ST Rifle, new Rail Detonator and Veamon skin will look wrong!
Sadly, the patch isn't (yet) MotS compatible, so those errors will still linger in the mod if you use it in MotS.
I love that it's compatible online though (you can play with others regardless of if they have the mod installed or not!).
Just keep in mind if you want others to see the other "bonus skins" (like Boc, Maw, Stormtrooper commander, etc) everyone needs JKE installed...
